Where did you get the idea that 2 people at a 90degree angle from each other wouldn’t both see the boat disappear ? Ofc they would, as well as every other person in all the possible angles in between them.
thats interesting, care to show some evidence of that - with the same boat
so lets be clear - for directional purposes lets make the entire lake the shape of a clock (you know round) at least 20 miles diameter too and then one person is on the shore at 3 o'clock and the other is at 6 o'clock and the boat travels from 6 o'clock to 12 o'clock and lets see what they each see - the same thing right? Any bets?
